This Tulipmania is often presented as the first economic boom and bust... but how accurate is that claim? What really happened? Join Ben and Noel as they separate the fact from fiction.

With 600,000 words and 3 million quotations, the Oxford English Dictionary is a massive tome. Work began on the dictionary in 1857, but the first edition wasn't published until 1884. Compiling the dictionary was a Herculean task, and James Murray, the editor of the dictionary, put out a call for assistance. This early crowdsourcing strategy worked surprisingly well.

So impressed, in fact, that Murray decided he had to meet the man in person. It's safe to say the meeting didn't go as expected.

A necropolis in what is now Northern Italy holds a strange and, at first glance, terrifying corpse. A Lombard man, aged somewhere between 40 and 50 years old, lost his right arm in a brutal accident. Normally this sort of wound would be a death sentence, but in this case the guy didn't just survive -- he created a prosthetic limb from a sword and officially became Knife Hand (a title we gave him because we think it sounds cool). Listen in to learn more about the life and times of Knife Hand, including why his story, when you get down to the details, is more an inspiring testament to human compassion than a frightening tale of a killer with a blade for an arm.

Join Ben and Noel as they explore the strange tale of the Mummies of Guanajuato.
